FLY-REMOVING DEVICE.

Application led December 22, 1911.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, GEORGE S. MCNEIL, a citizen of the United States,residing at New York city, New York, have invented certain new anduseful Improvements in Fly-Removing Devices, of which the following is aclear, full, and exact description.

This invention relates to an improvement in devices for the removal offlies either from the house or any other inclosure.

The present device may be suitably applied to a screen door or window,and preferably one that serves as a closure across a fairly well lightedopening.

In the construction of the present device, advantage is taken of thenatural propensity7 of flies to always crawl upwardly upon anyvertically disposed surface, particularly any well lighted surface, suchas a screen placed in a window.

The principle according to which my improvement is constructed and thepreferred embodiment of the same, will clearly appear from the followingspecification, and the scope of the invention more particularly pointedout in the appended claims.

Referring to the drawings Figure 1 is a front elevation of the entiredevice; Fig. 2 is a vertical section of the same through line 2--2 ofFig. l; Fig. 3 is a horizontal section of the same through line 3-3 ofFig. l; and Fig. 4 is a detailed perspective of the outlet opening.

Referring more particularly to the drawings, 1 indicates the wire meshof any suitable vertically disposed screen such as is usually placedover a window. Said screen may have a border frame 2 adapted to bemounted within the window frame 3, and adjacent to its upper end isformed a slotted opening 6 adapted to provide an outlet through whichflies will be induced to crawl by reason of the particular constructionhereinafter described. The outlet 6 is preferably of restrictedproportions being sulficiently wide to allow a fly to crawltherethrough, and the adjacent portion 4 of the screen below the outlet6 is offset outwardly as shown to a greater extent than the upperadjacent portion 5 of said screen, whereby said outlet 6 is disposedhorizontally. The outlet 6 and the adjacent offset portion 4 may besuitably stamped or formed by an embossing tool in the manufacture ofthe screen and the rough bordering edges of the outlet 6 are preferablyprotected by caps of smooth material such as 7 and 8, whereby the flymeets with no obstructions in his travel.

In addition to the horizontally disposed out-let 6 at the upper end ofthe screen, there is preferably an inner screen portion 9 spaced fromthe upper part ofthe main or outer screen and terminating at its lowerend below the outlet 6, all as clearly shown 1n Fig. 2. The inner screenportion 9 is also removably mounted upon the outer screen portionpreferably by tenon and grooved sides as shown in Fig. 3, whereby is maybe easily removed for cleaning the mam screen.

In use the present device will act as follows: The flies alighting uponthe screen 1 will naturally crawl upwardly along the same into the spacebetween the inner screen portion 9 and outer screen l, and their stepswill naturally be directed toward the outlet 6 so that they will passout through the same. Any flies which pass around the ends of outlet 6will find themselves between two screen portions which practically forma trap, leaving the outlet 6 as the most successful means of escape. Ihave found that the natural tendency of flies to travel upwardly alongsuch inclosing surfaces will prevent their escaping under the lower endof the inner screen portion 9 rather than by the outlet 6, and this sametendency also prevents flies on the other side of the screen fromalighting on the outside of the same and traveling downwardly throughthe outlet 6, and even if this should occasionally occur, such flieswill find themselves within the trap formed by inner screen portion 9,and would eventually escape back through the outlet 6 rather than intothe room.

It is obvious that the outlet 6 may be longer in extent if desired thanthat herein shown, and that many other variations in the formandproportions of parts in my device may be made without departing from thespirit or scope of my invention as defined in the appended claims.

What I claim is:

l. A fly removing device comprising a vertically disposed screen havinga portion offset adjacent its upper end to form a horizontally disposedoutlet, an inner screen portion spaced from the upper part of said outerscreen and terminating below said outlet.

2. A fly removing device comprising a vertically disposed outer screenhaving a narrow slot through its upper end with the adjacent portion ofsaid screen below said slot otfset outwardly to form a horizontallydisposed outlet, an inner screen portion removably mounted at the upperpart of said outer screen terminating below said outlet and spacedtherefrom.

3. A fly removing device Comprising a verticallyy disposed outer screenhaving a narrow slot through its upper end with the adjacent portion ofsaid screen below sai-d 15 December, 1911.
